frame with label

</dd>
<dt> <h3>Inherits</h3></dt><dd>
<a href="MegaWidget.html">Pmw.MegaWidget</a><br>
</dd>
<dt> <h3>Description</h3></dt><dd>
<p>
This megawidget consists of an interior frame with an associated
label which can be positioned on any side of the frame. The
programmer can create other widgets within the interior frame.</p>
<p></p>
</dd>
<dt> <h3>Options</h3></dt><dd>
Options for this megawidget and its base
classes are described below.<p></p>
<a name=option.labelmargin></a>
<dl><dt> <strong>labelmargin
</strong></dt><dd>
Initialisation option. If the <strong>labelpos</strong> option is not <strong>None</strong>, this specifies the
distance between the <strong>label</strong> component and the rest of the
megawidget. The default is <strong>0</strong>.</p>
</dd></dl>
<a name=option.labelpos></a>
<dl><dt> <strong>labelpos
</strong></dt><dd>
Initialisation option. Specifies where to place the <strong>label</strong> component. If not
<strong>None</strong>, it should be a concatenation of one or two of the
letters <strong>'n'</strong>, <strong>'s'</strong>, <strong>'e'</strong> and <strong>'w'</strong>. The first letter
specifies on which side of the megawidget to place the label.
If a second letter is specified, it indicates where on that
side to place the label. For example, if <strong>labelpos</strong> is <strong>'w'</strong>,
the label is placed in the center of the left hand side; if
it is <strong>'wn'</strong>, the label is placed at the top of the left
hand side; if it is <strong>'ws'</strong>, the label is placed at the
bottom of the left hand side.</p>
<p> If <strong>None</strong>, a label component is not created. The default is <strong>None</strong>.</p>
</dd></dl>
<a name=option.sticky></a>
<dl><dt> <strong>sticky
</strong></dt><dd>
Initialisation option. The default is <strong>'nsew'</strong>.</p>
</dd></dl>
</dd>
<dt> <h3>Components</h3></dt><dd>
Components created by this megawidget and its base
classes are described below.<p></p>
<a name=component.hull></a>
<dl><dt> <strong>hull
</strong></dt><dd>
This acts as the body for the entire megawidget. Other components
are created as children of the hull to further specialise this
class. By default, this component is a Tkinter.Frame.</p>
</dd></dl>
<a name=component.label></a>
<dl><dt> <strong>label
</strong></dt><dd>
If the <strong>labelpos</strong> option is not <strong>None</strong>, this component is
created as a text label for the megawidget. See the
<strong>labelpos</strong> option for details. Note that to set, for example,
the <strong>text</strong> option of the label, you need to use the <strong>label_text</strong>
component option. By default, this component is a Tkinter.Label.</p>
</dd></dl>
<a name=component.labelchildsite></a>
<dl><dt> <strong>labelchildsite
</strong></dt><dd>
The frame which can contain other widgets to be labelled. By default, this component is a Tkinter.Frame.</p>
</dd></dl>
</dd>
<a name=methods></a>
<dt> <h3>Methods</h3></dt><dd>
Only methods specific to this megawidget are described below.
For a description of its inherited methods, see the
manual for its base class
<strong><a href="MegaWidget.html#methods">Pmw.MegaWidget</a></strong>.
<p></p>
<a name=method.interior></a>
<dl><dt> <strong>interior</strong>()</dt><dd>
Return the frame within which the programmer may create widgets.
This is the same as <code>component('labelchildsite')</code>.</p>
</dd></dl>
